Abstract
The making process of silicone rubber O-ring includes the following steps: extruding silicone rubber strip in an extruder, baking, cutting, forming ring and painting liquid silicone rubber in the joint, sulfurizing, baking to form the silicone rubber O-ring. The silicone rubber O-ring has high tensile strength, low production cost, high quality and other advantages.
Description
Technical field:
The present invention relates to the manufacture method of silicone rubber O-ring.
Background technology:
The use of silicone rubber O-ring in daily life and industrial production is very extensive, and the silica gel sealing ring of existing traditional market all is that to adopt moulding press to extrude one-body molded, and adopts the cost of this technology higher and production efficiency is slower.In addition, adopt moulding press to extrude the sealing ring that integrated processes is come out, it is broken than being easier to, so adopt this technology will influence the quality of product.
Summary of the invention:
The objective of the invention is to provide the manufacture method of silicone rubber O-ring, save cost, improve the quality of products, promote production efficiency at the deficiencies in the prior art.
For achieving the above object, the present invention adopts following technical scheme:
It may further comprise the steps:
A, silicon rubber added vulcanizing agent after, via sending into extruder after the mill pressure rolling evenly, extrude silica gel strip;
B, with the silica gel strip extruded through drying tunnel baking back collection, put into baking box again and leave standstill baking;
C, the silica gel strip after will toasting are cut into Len req, surround circle, and are coated with liquid-state silicon gel cutting out incision, insert then to connect in the mould, mould is put into small-sized vulcanizer vulcanize;
D, cut mouthful after junctions of forming prune two, put into the oven for baking moulding again.
The temperature of described drying tunnel is 300 ℃-600 ℃, and silica gel strip is 10-60 second through the time of drying tunnel.
The temperature of described baking box is 180 ℃-200 ℃, toasts 2-4 hour.
130 ℃-180 ℃ of the temperature of described vulcanizer, cure time 50-80 second.
The baking temperature of described step D is 180 ℃-200 ℃, 1 hour time.
Beneficial effect of the present invention is: extrude silica gel strip by extruder earlier, and then through the baking processing, it is circular to cut back wall, coat liquid-state silicon gel in the junction, vulcanize, toast processing again, make silica gel strip form silica gel sealing ring, and this silica gel sealing ring is to adopt same material to connect; Through the finished product experiment, the silicone rubber O-ring that adopts manufacture craft of the present invention to produce has bigger tensile strength, and the intensity of junction is greater than other positions; Adopt that technology cost of the present invention is lower, product quality is better.
The specific embodiment:
The present invention includes following steps:
After earlier silicon rubber being added vulcanizing agent,, extrude silica gel strip via sending into extruder after the mill pressure rolling evenly;
Then the silica gel strip of extruding is collected after the drying tunnel baking, put into baking box again and leave standstill baking, the temperature of described drying tunnel is 300 ℃-600 ℃, and silica gel strip is 10-60 second through the time of drying tunnel, and the temperature of described baking box is 180 ℃-200 ℃, toasts 2-4 hour;
Silica gel strip after will toasting again is cut into Len req, surround circle, and be coated with liquid-state silicon gel cutting out incision, insert then and connect in the mould, mould is put into small-sized vulcanizer to be vulcanized, 130 ℃-180 ℃ of the temperature of described vulcanizer, cure time 50-80 second, and cut two after solidifying by liquid-state silicon gel and mouthful link together;
Cut mouthful after junctions of forming prune two, put into the oven for baking moulding again, described baking temperature is 180 ℃-200 ℃, 1 hour time, promptly forms the silicone rubber O-ring that intensity is strengthened this moment.
The present invention adopts extruder to extrude silica gel strip, and segmentation carries out step up cure in small-sized vulcanizer, simplified production technology, and greatly reduced production cost, and the connection of sealing ring adopts liquid-state silicon gel, promptly adopts same material to connect; Through the finished product experiment, the silicone rubber O-ring that adopts manufacture craft of the present invention to produce has bigger tensile strength, and the intensity of junction is greater than other positions; The present invention has that cost is lower, product quality better, production efficiency is than advantages such as height.
